The infiltration capacity curve graphically depicts how infiltration capacity changes over time post-rainfall; this curve was formulated by ____________________?
Show answer Hide answer
Answer: B. Horton
Explanation
Horton formulated the famous infiltration capacity curve describing how soil infiltration capacity decreases exponentially during rainstorms. Horton equation models the reduction from high initial infiltration capacity to a constant final steady-state rate. Empirical curve fitting allows hydrologists to apply Hortons infiltration parameters to watershed runoff simulation models. Infiltration capacity represents the maximum rate at which a given soil profile can absorb incoming rainfall water. Soil surface sealing, clay swelling, and capillary suction reduction cause infiltration rates to drop over time. Hortons infiltration model remains a classic benchmark in empirical hydrology and watershed flood forecasting.
Flood forecasting computer models incorporate Horton infiltration curves to calculate effective rainfall excess volumes accurately. Agricultural drainage engineers use infiltration timing models to prevent waterlogging and crop root asphyxiation. Understanding soil infiltration curves helps urban planners design sustainable stormwater management detention basins. Darcy formulated foundational laws governing groundwater flow through porous media rather than surface infiltration curves. Lacy developed regime channel design theories for stable alluvial canals rather than soil infiltration equations. Kennedy formulated critical velocity equations for designing non-silting irrigation canals in alluvial soils.
